LightWalker Dental Laser

Hard & Soft-Tissue Dental Lasers

Virtually Unlimited Applications

Designed for ultimate versatility, LightWalker lasers provide one of the most comprehensive lists of clinical applications available on any dental laser. With both tipped and tipless hand-pieces, your clinical options are almost endless.

LightWalker Dental Lasers offer the highest standard of dental treatment, and at the same time simplicity of use in:

  • Conservative Dentistry,
  • Endodontics,
  • Periodontics,
  • Soft-tissue Surgery,
  • Implantology,
  • Aesthetic Treatments.

A choice of three separate models, ensures a LightWalker laser system ideally suited to your needs:

The 20-watt LightWalker AT and the mid-level 8-watt LightWalker DT models both combines Er:YAG and Nd:YAG in a single package offering the ultimate in power and flexibility; while the entry-level, single-wavelength 8-watt LightWalker ST-E model still knocks the competition for six.

Presettings for 80 Different Applications

A simple menu of pre-programmed laser treatments, instinctively driven via the LightWalker touchscreen control interface.

Just choose the treatment and the laser automatically sets your optimum starting parameters. With easy-to follow protocols and touch-of-a-button treatment settings, you’ll be able to perform every dental procedure with confidence and high success rates, bringing in extra income to your practice along the way.

You can even upgrade the AT model to perform aesthetic skin treatments such as skin rejuvenation and removal of benign and vascular lesions.

Unparalleled Ease of Use

Easy-to-use touch screen

The LightWalker incorporates an easy-to–use colour touch-screen, with an adjustable tilt along with 80 customizable pre-settings covering more than 40 different applications.

Weightless OPTOflex® arm (available with LightWalker AT)

Unique to Fotona Laser systems, the LightWalker’s patented OPTOflex® Er:YAG articulated arm transmits a high-power laser beam to the hand-piece, while maintaining the quality of the laser beam to ensure precision and repeatability even at the highest settings.

The OPTOflex® arm is perfectly balanced during use; making hand-pieces completely weightless in your hand. OPTOflex® allows a maximum degree of control and  full range of motion, therefore allowing smooth manoeuvring of the hand-piece and improving treatment precision and ease.

Easy access spray/heated water reservoir

The integrated spray water container means that you don’t have to rely on any water mains outlet, making your laser system exceptionally mobile and hassle-free. The container is handily located at the back of the system for easy access for refilling. In addition, the water is heated to body temperature, avoiding cold sensitivity reactions during procedures.

Wireless foot-switch

LightWalker also has an optional wireless foot-switch for laser activation. This avoids unnecessary tangling and any potential trip hazard.

Built for efficacy and safety

In the LightWalker Dental Laser series, both the Erbium:YAG and the Nd:YAG “gold standard” laser wavelengths are produced by solid crystal lasers that can significantly outperform Diode lasers in terms of both the peak power generated and the range of pulse durations available to choose from.

Fast efficient cutting with unmatched patient comfort

With the advent of Fotona's QSP (Quantum Square Pulse) technology and higher output power, the LightWalker AT S has established new standards for ablation and cutting speed. This accelerated cutting speed provides LightWalker users with the speed and precision demand of a modern dental practice, while simultaneously increasing patient comfort.

Precise tissue surgery with simultaneous disinfection

To complement the superior power and speed detailed above; the homogeneous absorption of the Nd:YAG laser in soft tissue results in controlled tissue vaporization with simultaneous coagulation, for superior healing and disinfection.

Advanced Hand-piece Technology

Titanium Hand-piece Technology – for Unmatched Durability

All of the LightWalker Dental Laser models feature advanced titanium hand-pieces that provide robust durability for constant handling and frequent sterilization.

Lightwalker's tipped and tipless Er:YAG hand-pieces have an integrated air/water spray with adjustable water temperature for additional patient comfort, together with a quick-disconnect system for greater convenience and easier sterilization.

To date, over 15 specialized hand-pieces are compatible with LightWalker systems.

Automatic Hand-piece Detection – for Ease of Use

The LightWalker AT / AT S system comes equipped with two Nd:YAG hand-pieces, providing two different fibre diameters constantly available at your disposal.

In addition, the LightWalker AT Laser system has an automatic hand-piece detection system which knows exactly which hand-piece you have picked up and automatically restores the last-saved parameters for that hand-piece.

X-Runner™ –  for New Treatment Possibilities

The LightWalker AT / AT S is the first Erbium-based dental laser on the market to have digitally controlled hand-piece technology, providing dentists with entirely new treatment possibilities and unmatched levels of precision that have not been seen before in the world of dentistry

Green Pointing Beam – for Improved Visibility

Introduced specifically for Dental Surgeons, this optional feature for LightWalker AT S helps provide improved visibility over standard red-pointing beams when performing oral surgery.

Lightwalker Models Compared

Three models to choose from, according to your budget and clinical needs.

Lightwalker Models Compared

The AT and DT LightWalker models are equipped with dentistry’s two most effective laser wavelengths; namely, Er:YAG and Nd:YAG for no-compromise dentistry.

Since different oral tissues react in different ways to different laser wavelengths, it is goign to be a clinical preference that you have a choice of laser wavelengths on your dental laser. With the choice of two complementary wavelengths (in terms of their effect on tissues) LightWalker is seen as a “universal” laser. Practically all laser-assisted dental treatments can be performed with either the most highly absorbed Er:YAG laser wavelength or the most homogeneously absorbed Nd:YAG laser wavelength.

The combination of the two optimum wavelengths in one laser system enables Dental Practitioners to perform not only single-wavelength but also dual-wavelength (TwinLight®) treatments. Being able to use both wavelengths in a treatment makes optimum use of the unique laser-tissue interaction characteristics of each wavelength. For example, Nd:YAG laser energy is superior for coagulation and deep disinfection, while Er:YAG is uniquely efficient at ablating hard and soft tissues.

Combined, they can greatly expand the range of treatment possibilities and dramatically improve the outcome of laser assisted treatments.
